Sims 4 Kits vs Sims 3 Store: Which one did it better and why?

I bought almost everything from the Sims 3 store but now it won't load because EA and I had password and name/email changes hiccups during the time (Origin)? and now doesn't recognise that I have bought anything from it and I had to download it all every time I played. I gave up.
Don't tell me to use Answers as they don't understand either, even on Chats.

Around those early internet times, internet providers had simple email addresses etc. as well as EA I believe and several of them plus my provider got pwned. (qv) and they had to up their game with stronger ones and passwords. We must have been more trusting in those times!
